Hand signal lamp



Sept. 2, 1930. A. DENOCENZO HAND SIGNAL LAMP Filed Dec. 6, 1926 INVENTOR, [Jena-e229 v 7ATTORNEY Patented Sept. 2, 1930 UNITED STATES PATENT OFFICE ANTONIO DENOCENZO, OF LOS ANGELES, CALIFORNIA HAND SIGNAL LAMP Application filed December 6, 1926. Serial No. 152,864.

' change of the device from a signal means to l a trouble lamp, and to provide a swltch control means whereby the lamp may be continuously energized for use as a trouble light without requiring manual holding of the switch in closed position.

A further object is to provide a hand signal device in which circuit wiring is so protected that a shorting of the circuit to any encountered concuctive obstacle is prevented.

Other objects and advantages will be made manifest in the following specification of an illustrated embodiment of the invention; it being understood that modifications, variations and adaptations may be resorted to within the spirit, scope and principle of the invention as here claimed.

Figure 1 is a perspective of the device.

Figure 2 is aview showing the signal applied to the left hand.

Figure 3 is a plan; parts being broken away.

Figure 1 is a cross-section of thehand-band and lamp mounting.

Figure 5 is a detail of the switch and its dog.

The device includes a hand-band formed of a tubular body which can be made of pliable material as inner and outer strips 2 and 3 and an inside lining pad 1, as of-felt, all stitched longitudinally at 5. To adapt the band to hands of reasonably different sizes any suitable means may be employed to connect spaced ends 6 of the band; such connecting means being shown as a piece of elastic 7.

A suitable lamp socket 10, for an electric bulb 11, has a flange or lug-part 12 which is solidly riveted at 13 to an insulator-base or disk 14 which carries a spring terminal 15 to be engaged by the respective lamp contact when the lamp is secured in the socket; a feed wire 16 being electrically secured to the contact 15, as by rivet 17.

The rivets secure the socket and its base 1 1 to the inner band strip 2, the outer strip 3 having an opening for the projection of the socket; which has an outer coat of insulation 18 to prevent short circuiting to an engaged conducting obstacle.

As shown in Fig. 1, a notch 20 is provided in that edge of the band which lies against the loose skin connecting the thumb to the first joint of the forefinger and a switch spring 21, Fig. 5, will lie ust under the thumb so that when this is pressed the switch will engage an insulated contact 22 of a Wire 23 which connects to the flange 12.

The switch 21 has a plate 25 fixed on the inner strip 2 and it has a circuit wire 26 to complete current circuit when the switch is closed.

It is desirable to use the device for a trouble lamp and in such case a clear (colorless) bulb is mounted in the socket 10. The band can be used on the hand or can be hung or laid, asmost convenient, about the apparatus or place of use, and in order to maintain a closed circuit a retainer or dog 27, arranged on the outside of the band, is movable to a position to press down and so hold the spring 21 which is preferably concealed under the outer strip 3 as shown in Fig. 1. The dog 27 is insulated from its supporting plate 25 so that no short circuit can be made by it to an obstacle.

The wires 1626 lead out as in a cable 30 and have a plug 31 for connection to appropriate conductors.

I It will be seen that the outer strip 3 forms a cover for the socket base and for the switch parts, and the lines 4 cover the rivets by which the metal parts are attached to the inner strip 2 to which the parts are secured before the cover strip 8 is stitched down.

lVhat is claimed is:

In a drivers traflic signal device; a bulb socket having an out-turned base flange, an insulating disk on which said flange rests, a central terminal contact fixed on the disc, a Wrist band inner strip, rivets securing the flange 01": the socket and the disc to said strip, and an outer band strip covering the flange and the disc and Whose margins are secured to the inner strip; an opening in the outer strip, said socket projecting through said opening, and an inside lining pad covering the inner band strip; the latter forming a foundation for the rivets.
